Our Boulevard model included a loft style bed in the guest bedroom. Kids could climb up the ladder and enjoy their own semi-private sleeping nook or play area. This home also had an elevator incorporated into the floor plan. The "elevator" area was a walk-in pantry, with conversion to an elevator later as an option.

This recent blog may help you some. Take into consideration what type of roof you have installed on your new home. A GAF Designer roof increases the value by 7%!!! http://blog.rockandtait.com/do-you-love-designing-your-dream-home/

The features can depend on the location of the home being built. As a contractor in Florida many features that are common can be centered around indoor/outdoor living. Having not only a pool but living area, dinining area, and kitchen. Pools with a built in bar and seating.

Consider your interest and center a feature around it. We have recently done a wine room with glass door and window to view from kitchen. In another home we did built in bunk beds along one wall in the tv room for sleep overs.
